Polysorbate 20 (Tween-20) ,sorbitan mono-9-octadecanoate poly(oxy-1,2-ethanediyl) derivatives, is used in the formulation of biotherapeutic products for both preventing surface adsorption and as a stabilizer against protein aggregation.

Tween 80 is a nonionic surfactant and emulsifier that reduces bacterial adherence and inhibits biofilm formation. Tween 80 is widely used as a co-solvent in pharmacology experiments because of its ability to enhance the solubility of compounds in the aqueous phase.

IMPDH2-IN-2 is a potent inhibitor of inosine 5'-monophosphate dehydrogenase (IMPDH) (Ki,app: 14 μM) and a potential anti-tuberculosis agent. IMPDH2-IN-2 has a moderate antibacterial effect with MIC values of 6.3 and 11 μM in minimal GAST/Fe and rich 7H9/ADC/Tween media, respectively. μM.

OH-Chol is a cationic cholesterol derivative.1 OH-Chol, as a component of lipoplexes with DOPE , has been used for siRNA delivery and gene silencing in MCF-7 cells, as well as in mice via intravenous injection, resulting in lipoplex accumulation in the liver. It has also been used in cationic nanoparticles in combination with Tween 80 to transfect pDNA and siRNA into PC3 mouse xenografts via intratumoral injection and with Tween 80 and folate-PEG2000-DSPE in a KB mouse xenograft model for intratumoral gene delivery.2References1.

O-2545 is a potent water-soluble central cannabinoid (CB1) and peripheral cannabinoid (CB2) receptor agonist with Ki values of 1.5 and 0.32 nM, respectively. Typically, cannabinoid agonists are highly lipophilic and require solubilization through surfactant agents or binding to water miscible substances like albumin, Tween 80, or Emulphor for use. When dissolved in saline, O-2545 has shown high efficacy in mouse behavioral models, administered either intravenously or intracerebroventricularly.
